How long does polanight last
Polanight whitening gel is used in a fitted tray for the wear time prescribed for its formulation, and results fade as new stains accumulate.
The short answer
Polanight is a professional take-home tooth-whitening gel containing peroxide, placed in custom trays so it contacts the enamel evenly. How long a syringe or whitening course lasts depends on the gel strength, tray coverage, prescribed wear time, and how often it is used.
How should whitening gel be placed and stored in its trays?
Follow the written tray schedule, keep the syringe sealed as directed, and place only the prescribed amount in each tooth compartment. Stop and contact the dental team if sharp sensitivity, gum whitening, burning, or persistent irritation develops.
What should you do if tray-related pain or irritation continues?
Arrange dental advice before continuing if pain, ulceration, or gum irritation does not settle after removing the trays. A dentist should also assess untreated decay, cracked teeth, leaking fillings, or gum disease before further whitening.
When should sensitivity or gum irritation be checked by a dentist?
Ask which Polanight formulation and wear schedule apply to your trays, how much gel belongs in each compartment, and what to do if sensitivity occurs. Ask when the trays or remaining gel should be reviewed.
What should you ask about gel amounts, wear time and sensitivity?
A whitening syringe is not the same as the lifetime of whitening results.
